I have this 3800X that has been working perfectly fine and tonight I turn on my system and no sound & no picture. if I reset the 3800X I get sound briefly but I never get a picture. when I look at my receiver it appears that the HDMI signal is toggling on and off, but it never locks in to produce video. This makes the third Roku device I've had in the last 2 to 3 months that has malfunctioned and stopped working. I have another one that periodically the audio disappears and you have to power cycle it to get it back working. I'm really starting to have my doubts about your product and if longevity.
